DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now in detail to the drawings, and to facilitate a more complete understanding of the present invention, a basic construction of a teller machine will be first described with reference to FIG. 1.

The teller machine mainly comprises a keyboard panel including numeral keys 1 and function keys 4, a central processor unit 3, and a printer 7. The function keys 4 include a "plus" key, a "minus" key, a "total" key, a "sub-total" key, a "paper feed" key, a "release" key, a "clear" key, a "list" key, a "previous balance" key, an "ordinary deposit" key, a "current deposit" key, a "fixed deposit" key, a "cash out" key, a "cash in" key, a "cash check" key, an "add print" key, a "reading and resetting of totals" key, a "miscellaneous" key, a "miscellaneous cash" key, a "duplicate" key , a "repeat" key, a "balance" key, a "print out" key, an "account number" key, and a "completion" key for indicating the completion of a specific transaction data entry.

Numeral information introduced through the numeral keys 1 is applied to the central processor unit 3 via a key encoder 2. A key determination circuit 5 is connected to the function keys 4 for determining the depressed key included in the function keys 4, thereby developing instruction commands to the central processor unit 3. The thus introduced information and the calculation result derived from the central processor unit 3 are stored in a primary memory 6.

When the introduction of the transaction data is completed, the "completion" key is actuated to indicate the completion of the data entry. Upon actuation of the "completion" key, the central processor unit 3 performs the check operation and, then, transfer the transaction data stored in the primary memory 6 to a primary print control circuit 8. The primary print control circuit 8 activates the printer 7 to print out the transaction data on a journal paper. The transaction data stored in the primary memory 6 is also applied to an update control circuit 10, which functions to update or accumulate the transaction data stored in an auxiliary memory 9. The transaction data stored in the auxiliary memory 9 is printed out through an auxiliary print control circuit 11 and the printer 7 at an operator's choice.

When the transaction data is desired to be printed out on a bill, a bill is inserted into the printer 7 and the "duplicate" key is actuated. Upon actuation of the "duplicate" key, the transaction data stored in the primary memory 6 is applied to the printer 7 through the primary print control circuit 8. The contents stored in the primary memory 6 are cleared when the following transaction data entry operation is conducted.

In the above-mentioned teller machine, the ordinary deposit transaction is, usually, most frequently handled. In the conventional teller machine, the "ordinary deposit" key must be actuated each time when the transaction data is introduced even though the ordinary deposit data entry is continuously repeated. The present invention is to provide a novel key input system which can minimize the key actuation when the same kind of transaction is continuously repeated.

FIG. 2 is a block diagram of a teller machine including an embodiment of a key input system of the present invention. Like elements corresponding to those of FIG. 1 are indicated by like numerals.

The key input system mainly comprises a control circuit 36 for maintaining a specific transaction identifying signal. The control circuit 36 is connected, for example, to an "ordinary deposit" key "I".

Now assume that the ordinary deposit transactions for customers "A", "B" and "C" are continuously conducted.

First, an amount "a" received from the customer "A" is introduced into the central processor unit 3 through the numeral keys 1 and the key encoder 2. Then, the ordinary deposit key "I" is actuated to develop a high level logic signal "H" toward an AND gate 31 and a successive key actuation detection circuit 30. At this moment, the successive key actuation detection circuit 30 develops a low level logic signal "L" because the ordinary deposit key "I" is actuated only once. The low level logic signal "L" developed from the successive key actuation detection circuit 30 is applied to the AND gate 31 via an inverter 32. Accordingly, the AND gate 31 develops the key input signal corresponding to the ordinary deposit key "I" toward the key determination circuit 5 through an OR gate 33.

Thus, the central processor unit 3 handles the amount "a" as the ordinary deposit data. The thus introduced ordinary deposit data "a" is introduced and memorized in the primary memory 6. Then, the operator actuates a completion key 20 to print out the ordinary deposit data "a" on the journal paper through the primary print out control circuit 8 and the printer 7. At this moment, the ordinary deposit data "a" is added to the ordinary deposit data stored in the auxiliary memory 9 and the accumulated data is stored in the auxiliary memory 9 at the ordinary deposit memory section. A receipt bill is inserted into the printer 7 and a duplicate key 21 is actuated to print out the receipt bill to be handed to the customer "A".

Next, an amount "b" received from the customer "B" is introduced through the numeral keys 1. Then, the ordinary deposit key "I" is actuated to develop the high level logic signal "H" toward the successive key actuation detection circuit 30 and the AND gate 31. At this moment, the successive key actuation detection circuit 30 develops a high level logic signal "H" because the ordinary deposit key "I" is successively actuated for the customers "A" and "B". The high level logic signal "H" derived from the successive key actuation detection circuit 30 functions to disable the AND gate 31 via the inverter 32, and to enable another AND gate 34.

The other input terminal of the AND gate 34 receives a high level logic signal "H" derived from a numeral key actuation detection circuit 35 which develops the high level logic signal "H" when the numeral keys 1 are actuated. Accordingly, the key input signal corresponding to the ordinary deposit key "I" is applied to the key determination circuit 5 through the AND gate 34 and the OR gate 33. The remaining operation is similar to that is achieved in the case for the customer "A".

The numeral key actuation detection circuit 35 is reset to develop a low level logic signal "L" when any one of the function keys 4 is actuated. The successive key actuation detection circuit 30 connected to the ordinary deposit key "I" is reset when other transaction identifying keys such as a current deposit key "II", a fixed deposit key "III" and a miscellaneous key "IV", or the "clear" key are actuated.

Last, an amount "c" received from the customer "C" is introduced through the numeral keys 1. The numeral key actuation detection circuit 35 develops the high level logic signal "H" to activate the AND gate 34. Since the successive key actuation detection circuit 30 is set to develop the high level logic signal "H" by the preceding transaction data entry operation for the customer "B", the AND gate 34 develops the signal indicating the actuation of the ordinary deposit key "I" without actual actuation of the ordinary deposit key "I". The following operation is similar to that is achieved in the case for the customer "A".

Although in the foregoing embodiment the key actuation is conducted in the order of numeral keys → the transaction kind identifying key → the completion key → the duplicate key, the teller machine can be constructed to respond to the key actuation in the order of the transaction kind identifying key → numeral keys → the completion key → the duplicate key. In this case, the successive key actuation detection circuit 30 is not necessarily reset by the "clear" key.

The present key input system can be constructed through the use of microprocessor techniques.

The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications are intended to be included within the scope of the following claims.
